node red on 127.17.0.1:1880 because it is setup with into container.  
did the sudo pi gpiod into terminal  
set the port at 1880 into the gpiod output node  
I tried the default port at 8888 not better  
First time I hit the inject button I get the error  
when I hit again no error anymore but nothing happens on the pin which is a simple led plugged in  
I'm stuck.  
If someone has someting for me please thank you!  
did the command  
netstat -an | grep LISTEN | grep -v LISTENING  
tcp6 0 0 :::1883 :::\* LISTEN  
tcp6 0 0 :::9000 :::\* LISTEN  
tcp6 0 0 :::9001 :::\* LISTEN  
tcp6 0 0 :::2003 :::\* LISTEN  
tcp6 0 0 :::8083 :::\* LISTEN  
tcp6 0 0 :::53 :::\* LISTEN  
tcp6 0 0 :::8086 :::\* LISTEN  
tcp6 0 0 :::8888 :::\* LISTEN  
tcp6 0 0 :::1880 :::\* LISTEN  
tcp6 0 0 :::3000 :::\* LISTEN  
tcp6 0 0 :::8089 :::\* LISTE

When you started your container did you allow port 8888 to be mapped from inside to outside ?

Hi Jay,  
This is a good question.  
I did the install via Graham Garner IoTstack github setup.  
I should know but I don't sorry.  
That is what happens when you build on something you did not build yourself...  
Would you know how to verify that ?

I also did the  
npm install node-red-node-pi-gpiod  
command

Are you using a container for a reason? If not then I suggest you instead use the install script from the node-red docs  
[https://nodered.org/docs/getting-started/raspberrypi](https://nodered.org/docs/getting-started/raspberrypi)

Ok I changed to my raspbian regular setup and it worked. sorry about that. It must be a container knowledge issue.  
Thank you!

One of the reasons for using a container is that it is to some extent isolated from the rest of the system, which can be a good thing, sometimes it just gets in the way however.
